Research paper shows NJ diversity has increased, but not uniformly across the state

Galloway, New Jersey – New Jersey’s population has diversified over the past 20 years, but that diversity is not evenly distributed among the 21 counties, according to a student research paper released today by the William J. Hughes Center for Public Policy from the University of Stockton.

Stockton senior Emily Kramer’s article used census data to show the level of diversity found in the 2020 census for each county and how the Hispanic/Latino and non-Hispanic white, black and Asian populations have changed. in each group’s share. of the county population.

Kramer’s article was published on the Hughes Center website at The report is linked to an interactive map that details each county’s diversity ratings.

“This research paints a demographic picture of who we are as a state in terms of the ethnic and racial makeup of our counties,” said John Froonjian, director of the Hughes Center. “It also shows how different segments of our society make up larger or smaller percentages of our population, and where that growth is happening most rapidly.”

Kramer created a scoring system to measure levels of diversity that can be compared from county to county. The diversity index was based on the percentages of county populations that each group represented in 2020.

• The most diverse counties in New Jersey according to the Diversity Index are Cumberland, Essex, Hudson, Middlesex, Passaic, Somerset and Union counties

• Counties with moderate diversity are Atlantic, Bergen, Burlington, Camden, Mercer, and Morris counties

• The least diverse counties in New Jersey according to the index are Cape May, Gloucester, Hunterdon, Monmouth, Ocean, Salem, Sussex and Warren counties

Research has documented the level of growth or decline of whites, blacks, non-Hispanic Asians, and those of Hispanic/Latino descent based on US Census data.

New Jersey counties where people of Hispanic origin increased as a percentage of the population by more than 10 percentage points from 2000 to 2020 are:

• Bergen (11%), Cumberland (15%), Mercer (12%), Passaic (13%), Union (14%).

Asians increased as a percentage of the population by more than 10 percentage points during this period by:

• Hudson (19%), Mercer (11%), Middlesex (20%), Somerset (15%) counties.

Black residents have grown as a percentage of county populations at a slower rate than Asian and Hispanic groups. In Union County, the black population over the age of 20 increased by 10 percentage points as a share of the population pie. Growth in all other counties was in the single digits.

Whites declined as a percentage of the population in 13 of New Jersey’s 21 counties.

“It is important to analyze the new (population) trends that have occurred,” Kramer concluded in his article. “In order to deal effectively with voters, state officials and policy makers must know the characteristics of the communities they serve.”

Kramer holds a double major at Stockton in Political Science with a concentration in International Affairs and Language and Cultural Studies. she is also pursuing a minor in global studies. She is President of Stockton Amnesty International and Vice President of Stockton Model United Nations. Kramer will graduate in the spring of 2023 and hopes to attend law school to become an immigration attorney.
